A message on the DC board which mentioned infusing Vodka with Meyer lemons got me thinking.
What are your favorite alcohol infusion ideas? How long does the infusion need to sit before the flavor has really penetrated the alcohol?
I've always thought a good infusion idea would be to use hybiscus flowers with some fairly neutral spirit like vodka. They're traditionally boiled in water to create an Egyptian drink pronounced something like "Carkiday" (though I have no idea what its proper English spelling or transliteration would be), which tastes something like cranberry and is very refreshing when sweetened and cooled as a summer drink.
